Found possibly ancient object and can't find any info if it's valuable.

I recently bought a bone knife with jade chips on the handle. It is something that maybe they used before technology-- i.e. possibly cavemen or ancient. The knife is sharp and solid and could kill an animal or other human if need be. It could also be used for cutting. The jade chips make it easier to hold. I don't know, I found nothing like it on Worthpoint, and maybe quitting this site soon as is maybe worthless. I think it may have to be carbon dated to know if it is really valuable. Does anyone have any ideas that could help? Thanks
